Abstract

A method for filtering hydrocarbon contaminated water for separation and recovery of the contaminants and recirculation of the water, wherein the water contaminated by hydrocarbons is, in a series of successive stages, caused to flow down through a cushion of a filtering hydrocarbon that floats on a defined surface of a water body and is permitted to flow via an underflow into the free portion of the water body prior to transfer via an overflow to the next stage, and where, in a final stage, approximately anhydrous hydrocarbon is drawn off as overflow while hydrocarbon-free water is removed as underflow, is carried out with the aid of an apparatus which, in operable state, comprises a series of successive basins filled with water (2, 3, 4) separated by walls (22, 23), where an upper part of each basin is bounded by means of fixed partition walls (32, 33) projecting downward in the water and is filled with a filtering hydrocarbon (12, 13, 14), where the final cushion of filtering hydrocarbon (14) downstream is bordered by a vertically displaceable outlet bin (47) for the contamination enriched hydrocarbon, and further comprising a water outlet (5, 6, 7, 8) comprising two successive horizontal watercourses (5, 6), having a declining ceiling (10, 11) in the direction of flow, and thereafter a vertical S-pipe (7, 17) having an outlet (8).
